Pools are not unlike denominations - bodies of water cut off from the flowing source that once filled them, sitting to grow stagnant and sometimes bitter. People flock to them for refreshment in times of dryness, seek healing in the waters which a supernatural
stirring or movement can gift, or act as a place for opposing parties to sit either side and then get up to fight each other to the death.

It is awesome how God's wisdom describes a
living, flowing and yet very dividing river of his Spirit to create UNITY in his people. There is nothing like our GOD!! His ways are higher than our own.
